OpenTelemetry Meta Packages for Node

NPM Published Version Apache License

This module provides a simple way to initialize multiple Node instrumentations.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/auto-instrumentations-node

Usage

OpenTelemetry Meta Packages for Node automatically loads instrumentations for Node builtin modules and common packages.

Custom configuration for each of the instrumentations can be passed to the function, by providing an object with the name of the instrumentation as a key, and its configuration as the value.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { getNodeAutoInstrumentations } = require('@opentelemetry/auto-instrumentations-node');
const { CollectorTraceExporter } = require('@opentelemetry/exporter-collector');
const { Resource } = require('@opentelemetry/resources');
const { SemanticResourceAttributes } = require('@opentelemetry/semantic-conventions');
const { SimpleSpanProcessor } = require('@opentelemetry/sdk-trace-base');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const exporter = new CollectorTraceExporter();
const provider = new NodeTracerProvider({
  resource: new Resource({
    [SemanticResourceAttributes.SERVICE_NAME]: 'basic-service',
  }),
});
provider.addSpanProcessor(new SimpleSpanProcessor(exporter));
provider.register();

registerInstrumentations({
  instrumentations: [
    getNodeAutoInstrumentations({
      // load custom configuration for http instrumentation
      '@opentelemetry/instrumentation-http': {
        applyCustomAttributesOnSpan: (span) => {
          span.setAttribute('foo2', 'bar2');
        },
      },
    }),
  ],
});
